Access / Excel

Web App

SOUND FAMILIAR?

Is this you?

File is too big

The Access or Excel file is hitting size limits, slowing to a crawl, or corrupting on save.

Multi-user conflicts

Two people open it at once and one of them loses their work. Constant “file is locked” pop-ups.

Can’t open on Mac or phone

Sales is in the field, the warehouse is on a tablet, and nobody can get to the data.

The IT person left

The one who built it is gone, and nobody understands how it works.

Security / compliance pressure

Auditors are asking who has access, when, from where. You don’t have answers.

Version sprawl

There are six copies of the file on the shared drive and nobody knows which one is the real one.

WHAT YOU GET INSTEAD

Imagine instead…

Anywhere access

Same login from the office, home, a tablet, a customer site.

Real-time multi-user

Ten people editing the same data, no file locks, no lost work.

Mobile-responsive

Built for phone and tablet from the start — no extra app to install.

Role-based security

Sales sees sales. Finance sees finance. Admins see everything — per-user, audit-logged.

Audit trail

Every change is logged: who, what, when. Compliance ready.

Integrations

QuickBooks, Salesforce, Stripe, your warehouse system — talk to the tools you already use. Nothing to install.

HOW WE WORK

Our streamlined 6-step process

1
Free System Review & Scoping
Async-first. Send us your file. Optional 30-min review call on request — no charge. We tell you what we see and what it would take.
2
Architecture & fixed-price quote
We write up the architecture, data model, and integrations — then quote a fixed price. No surprises.
3
Iterative build with weekly demos
You see real working software every week. Course-correct early; never wait months to see progress.
4
Data migration + parallel run
We migrate your data and run the old system alongside the new one until you’re confident.
5
UAT
Your team runs through the new app, tests the workflows that matter, and signs off before launch.
6
Go-live & ongoing support
We flip the switch, monitor the rollout, and stay on call. Support is ongoing — you’re not on your own day one.

WHY YITTBOX

You’re in good hands

20+ years of MS Access & Excel

We’ve seen every variant of “the Access database that grew up.” Nothing surprises us.

Fixed-price quotes

We scope, then quote a number. No hourly bleed, no “a few more weeks.”

US-based team

Real people in your timezone. Demos when it’s convenient for you, not a 3am Zoom.

Weekly demos

You see what we built every week. No black boxes, no surprises at launch.

References on request

QUESTIONS

Frequently asked

What does it cost?

We provide a fixed-price quote after the free scoping call. Every project is scoped to your data, users, and integrations.

How long does it take?

Most projects ship in 6–12 weeks from scoping. The exact timeline is in your fixed-price quote — no “a few more weeks.”

Will we lose data?

No. We migrate your data into the new system and run the old system in parallel until you’ve verified everything against the new one. Nothing flips until you sign off in UAT.

Can we keep using Access during the transition?

Yes. During the parallel-run phase your team keeps working in Access or Excel exactly like today. We only ask you to switch over after UAT.

Do you sign NDAs?

Yes. Mutual NDA is standard before we look at your file. Send us yours or we’ll send you ours.

What about my existing reports?

Reports come over. We rebuild them in the new web app so they render in a browser and export to PDF/Excel on demand. The numbers stay the same.
